GSignal doesn't know anything about properties. For it ::blah is just
a string/quark. The interpretation of it as a property name is just a 
convention between those creating the signal and those connecting
to it.

You have to use this anyways; calling g_signal_emit_* on signals you
didn't create is generally not allowed.
